A method for distinguishing burst onsets of voiceless stop consonants in terms of place of articulation is described. Four speakers produced the voiceless stops in word-initial position in six vowel contexts. A metric was devised to extract the characteristic burst-friction components at burst onset. The burst-friction components, derived from the metric as sensory formants, were then transformed into log frequency ratios and plotted as points in an auditory-perceptual space (APS). In the APS, each place of articulation was seen to be associated with a distinct region, or target zone. The metric was then applied to a test set of words with voiceless stops preceding ten different vowel contexts as produced by eight new speakers. The present method of analyzing voiceless stops in English enabled us to distinguish place of articulation in these new stimuli with 70% accuracy.
描述了一种根据发音部位区分清塞音爆发起始的方法。四名说话者在六种元音语境中在单词开头位置发出清塞音。设计了一种度量方法来提取爆发起始时的特征性爆发-摩擦成分。从该度量方法中得出的爆发-摩擦成分作为感觉共振峰进行转换，然后转换为对数频率比，并绘制为听觉-感知空间（APS）中的点。在APS中，每个发音部位都与一个不同的区域或目标区域相关联。然后将该度量方法应用于由八名新说话者发出的、在十种不同元音语境之前带有清塞音的单词测试集。目前分析英语清塞音的方法使我们能够以70%的准确率区分这些新刺激中的发音部位。
